Description

Technical Field

[0001] This invention relates to the field of biofilter technology, and in particular to an automatic filling device for composite packing sponge blocks in biofilters. Background Technology

[0002] In the field of biofilter technology, composite packing materials are usually composed of an outer shell and a biological carrier material filled inside. Among them, sponge blocks are widely used as the internal filling material of composite packing materials due to their large specific surface area, high porosity, and easy attachment and growth of microorganisms. The preparation of this type of composite packing material involves inserting sponge blocks into a modular box according to the design requirements, and finally completing the splicing and closure of the box.

[0003] Currently, the filling of sponge blocks is mainly done manually. Workers need to grab the sponge blocks one by one and put them into the box according to the required quantity, then press and adjust them by hand, and finally put the two boxes together. This method involves many steps, is labor-intensive, and takes a long time to fill each time. In addition, the filling quantity and production efficiency are not automatically counted, which is not conducive to continuous production and intelligent management. Summary of the Invention

[0004] 1. The technical problem to be solved by the present invention

[0005] The purpose of this invention is to achieve precise quantitative filling based on weight by setting up a weighing device and control panel, automatically record the completed quantity, calculate production efficiency in real time, and improve the level of intelligent production management.

[0006] 2. Technical Solution

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

A discharge pipe is provided at the upper end of the base, and clamping plates are provided on both sides of the lower end of the discharge pipe. A second telescopic rod is provided at the rear end of the clamping plates. The second telescopic rod extends to push the clamping plates to contact and clamp the sponge falling from the discharge pipe to limit the sponge from falling. A first tray is provided in the middle of the base, and a first mounting groove is recessed at the upper end of the first tray. A second tray is provided on one side of the first tray, and a first pusher is provided on the other side of the first tray. A second pusher is provided at the lower end of the first mounting groove.

[0009] Preferably, the outer wall of the box is mesh-like, and an insert block is provided on the side of the first mounting groove. A third telescopic rod is provided at the rear end of the insert block. When the third telescopic rod is extended, it can push the insert block into the mesh outer wall of the box. Movable arms are provided at the front and rear ends of the second tray, and second support arms are provided at the front and rear ends of the first mounting groove. The second support arms and the movable arms are rotatably connected through a second connecting shaft. The insert block can be firmly fixed in the first mounting groove by embedding it into the mesh outer wall, so as to avoid displacement during subsequent sponge filling and box splicing.

[0010] Preferably, there are two boxes, which are placed in the second tray and the first mounting slot respectively. The rotation of the second tray can drive the box placed on it to move closer to the box placed in the first mounting slot and complete the splicing. Through the rotation of the second tray, the two boxes are automatically aligned and spliced, which replaces the manual closing operation and improves the splicing efficiency and consistency.

[0011] Preferably, the side of the first pusher facing the first mounting groove is provided with a groove that matches the curvature of the outer wall of the box. The rear end of the first pusher is provided with a first telescopic rod, and the lower end of the second pusher is provided with a fourth telescopic rod. The first pusher and the second pusher work together to push the filled box assembly out of the first mounting groove from the bottom and the side, respectively, realizing automatic unloading of the finished product without manual intervention.

[0012] Preferably, a first transmission pipe is provided between the two second telescopic rods. The outer wall of the second telescopic rod is fixed to the outer wall of the first transmission pipe, and a clamp is installed on the inner wall of the first transmission pipe. The telescopic position of the second telescopic rod passes through the first transmission pipe and is fixedly connected to the clamp. The first transmission pipe includes a vertical section and an inclined section. A rotatable roller is provided near the discharge port of the inclined section. The roller is used to control the discharge state of the sponge block, reducing the number of parts and reducing the space occupied by the equipment. The roller converts the continuously sliding sponge block into a single output, creating conditions for subsequent accurate measurement.

[0013] Preferably, the outlet of the inclined section of the first transmission pipe is connected to a second transmission pipe, the outlet of the lower end of the second transmission pipe is located above the first mounting groove, and a weighing device is installed inside the second transmission pipe through the first connecting shaft. The weighing device can detect the cumulative weight of the sponge blocks in real time, and issue a control signal when the preset value is reached to achieve precise control of the number of sponge blocks. The weighing device can rotate and tilt around the first connecting shaft to facilitate the smooth falling of the sponge blocks.

[0014] Preferably, the front end of the base is detachably provided with a first storage box. The first storage box is used to collect the finished product boxes after they have been filled. The detachable design makes it convenient for operators to take out the finished products and improves the ease of operation.

[0015] Preferably, a second storage box is provided at the upper end of the discharge pipe, and a shock-absorbing device is provided between the second storage box and the base. A vibration motor is fixed on the second storage box. The vibration motor generates high-frequency micro-amplitude vibration, which can effectively prevent the sponge blocks from bridging or sticking in the second storage box, ensuring smooth material supply. The shock-absorbing device isolates vibration transmission and avoids interference with the downstream weighing accuracy.

[0016] Preferably, the two boxes are connected by a connecting strip. One of the boxes has a connecting block on its outer wall with an installation hole inside. The other box has a connecting end on its outer wall corresponding to the connecting block. The connecting end is V-shaped. The two boxes can be connected by inserting the connecting end into the installation hole inside the connecting block. The pre-connection of the two boxes is achieved by the connecting strip. The locking structure between the connecting end and the connecting block has an elastic self-locking function, making the splicing firm and reliable without the need for additional fasteners.

[0017] Preferably, the base is also provided with a control panel.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0020] 1. This invention achieves automated quantitative supply of sponge blocks by setting up a discharge pipe, clamping plates, a second telescopic rod, a first transmission pipe, rollers, a second transmission pipe, and a weighing device. In use, the second telescopic rod drives the clamping plates to retract and open the lower end of the discharge pipe. The sponge blocks slide down along the first transmission pipe, and the rollers rotate to discharge the sponge blocks one by one. The weighing device detects the cumulative weight in real time and provides feedback control to stop the rollers from rotating and reset the clamping plates when the preset value is reached. This achieves accurate measurement and intermittent release of the sponge blocks. At the same time, the target weight value is input through the control panel. The counter automatically accumulates after each accurate tilting of the weighing device. This process replaces the traditional manual grabbing and pressing operations, reducing labor intensity.

[0021] 2. This invention, through the arrangement of a first tray, a second tray, a first pusher, a second pusher, an insert block, a third telescopic rod, and a movable arm, achieves automatic positioning, flipping and splicing of the box, and unloading of the finished product. In use, the insert block is embedded in the mesh outer wall of the box in the first mounting groove to fix it. The movable arm drives the second tray to flip, bringing the two boxes closer together and completing the splicing through the cooperation of the connecting end and the connecting block. Subsequently, the first pusher and the second pusher work together to push the finished product into the first storage box. This process integrates box fixing, sponge filling, box splicing, and finished product unloading into the same station, reducing manual intervention, improving filling efficiency, and meeting the needs of continuous production.

[0033] The present invention will be further described below with reference to specific embodiments.

[0034] like Figure 1As shown, an automatic filling device for composite filler sponge blocks in a biological filter, according to this embodiment, includes a base 1 serving as the installation foundation and a box 26 for accommodating sponge blocks. A vertically extending discharge pipe 15 is fixedly connected to the upper end of the base 1. Two opposing clamping plates 16 are provided at the lower outlet of the discharge pipe 15, with the two clamping plates 16 located on both sides of the outlet of the discharge pipe 15. A second telescopic rod 17 is connected to the rear end of each clamping plate 16. In use, when the second telescopic rod 17 is extended, it can push the clamping plates 16 to move towards the central axis of the discharge pipe 15, so that the two clamping plates 16 clamp the sponge blocks falling from the discharge pipe 15 from both sides, using friction to prevent the sponge blocks from falling further. When the second telescopic rod 17 retracts, the clamping plates 16 release, and the sponge blocks can continue to fall by gravity. By controlling the extension and retraction of the second telescopic rod 17, intermittent quantitative release of sponge blocks can be achieved.

[0035] A first tray 9 is fixedly installed in the middle of the base 1. The upper end surface of the first tray 9 is recessed to form a first mounting groove 18. The outline of the first mounting groove 18 is adapted to the shape of the box 26 and is used to position and place the first box 26. A second tray 21 is provided on one side of the first tray 9 on the base 1, and a first pusher 10 is provided on the other side of the first tray 9.

[0036] In this embodiment, as Figure 8 and Figure 9 As shown, a plug 25 is provided in the first mounting groove 18. The rear end of the plug 25 is connected to a third telescopic rod 30. In use, when the third telescopic rod 30 extends, it can push the plug 25 into the first mounting groove 18, so that the front end of the plug 25 is embedded in the mesh outer wall of the box 26 placed in the first mounting groove 18, thereby fixing the box 26 and preventing it from shifting during subsequent sponge filling or splicing.

[0037] Movable arms 20 are provided at the front and rear ends of the second tray 21, and second support arms 19 are provided at the front and rear ends of the first mounting groove 18. The second support arms 19 and the movable arms 20 are hinged together by the second connecting shaft 22. With this hinged structure, the second tray 21 can rotate relative to the first tray 9 around the second connecting shaft 22, thereby driving the box 26 placed on it to move closer to the box 26 in the first mounting groove 18 and complete the splicing.

[0038] Correspondingly, such as Figure 6 and Figure 7As shown, the first pusher 10 has an arc-shaped groove on the side facing the first mounting groove 18. The curvature of the groove matches the curvature of the outer wall of the box 26. The rear end of the first pusher 10 is connected to a first telescopic rod 11. A second pusher 23 is also provided below the first mounting groove 18. The lower end of the second pusher 23 is connected to a fourth telescopic rod 31. The front end of the base 1 is detachably inserted into a first storage box 2 for collecting the two boxes 26 after they have been filled. When the two boxes 26 are joined together, the fourth telescopic rod 31 extends to drive the second pusher 23 to move upward, lifting the two joined boxes 26 upward from the bottom. Then the first telescopic rod 11 extends to drive the first pusher 10 to move towards the first mounting groove 18, using its arc-shaped groove to push the assembly from the side, causing it to detach from the first mounting groove 18 and fall into the first storage box 2 below.

[0039] A first transmission pipe 6 is disposed between the two second telescopic rods 17. The first transmission pipe 6 is curved in shape and includes a vertical section and an inclined section. The outer wall of the second telescopic rod 17 is fixedly connected to the outer wall of the first transmission pipe 6. Figure 5 As shown, the clamp 16 is installed on the inner wall of the first transmission pipe 6, and the telescopic end of the second telescopic rod 17 passes through the pipe wall of the first transmission pipe 6 and is fixedly connected to the clamp 16. This integrated structure makes the clamping mechanism and the conveying channel form an integrated design, with a compact structure and small space occupation.

[0040] like Figure 3 As shown, a rotatable roller 13 is provided near the outlet of the inclined section of the first transmission pipe 6. The outer wall of the roller 13 is provided with anti-slip texture or protrusions. When the sponge block slides down the first transmission pipe 6 to the roller 13, the roller 13 is driven to rotate by an external motor. Through friction, the sponge blocks are discharged one by one, thereby converting the continuously sliding sponge blocks into discrete single blocks for easy subsequent counting and weighing.

[0041] like Figure 2 and Figure 4 As shown, a second transmission pipe 7 is connected to the outlet of the inclined section of the first transmission pipe 6. The lower outlet of the second transmission pipe 7 is located above the first mounting groove 18. A weighing device 14 is hinged inside the second transmission pipe 7 through the first connecting shaft 12. The weighing device 14 can be a high-precision electronic scale module.

[0042] The weighing device 14 is initially in a horizontal position and is used to receive the sponge block falling from the second transmission pipe 7. When the accumulated weight reaches the preset value, it sends a command to the motor connected to the first connecting shaft 12 to drive the weighing device 14 to rotate and tilt around the first connecting shaft 12, so that the sponge block falls into the designated position below.

[0043] In this embodiment, to ensure precise filling of sponge blocks according to a set quantity, a total weight-based control strategy is adopted. The operator can pre-set a target weight value in the control panel 32 based on the average weight of a single sponge block and the target filling quantity. For example, if the average weight of a single sponge block is 0.2 grams, and 8 sponge blocks need to be filled into the box 26, the total target weight of the sponge blocks is 1.6 grams. The operator inputs the target weight value of 1.6 grams through the control panel 32. After the equipment is started, the weighing device 14 monitors the number of sponge blocks it carries in real time. When the accumulated weight reaches 1.6 grams, the weighing device 14 immediately sends a control signal to the drive motor of the roller 13 and the second telescopic rod 17. The roller 13 stops rotating, and the second telescopic rod 17 pushes the clamping plate 16 to clamp the sponge block in the discharge pipe 15, thereby interrupting the feeding. Subsequently, the weighing device 14 rotates and tilts around the first connecting shaft 12, loading the eight precisely measured sponge blocks into the box 26 in the first mounting groove 18 at once. This loading method based on weight to infer the quantity avoids the errors that may be caused by deformation or adhesion of the sponge blocks due to direct counting.

[0044] In order to fix the second transmission tube 7, the outer wall of the second transmission tube 7 is connected to the base 1 by the first support arm 8.

[0045] The upper end of the discharge pipe 15 is connected to a second storage box 3, which is used to pre-store the sponge blocks to be filled. The interior of the second storage box 3 is equipped with a stirrer 5. When a blockage occurs inside the second storage box 3, the stirrer 5 can agitate the second storage box 3 to clear the blockage inside.

[0046] A shock-absorbing device is provided between the second storage box 3 and the base 1. The shock-absorbing device is a shock absorber.

[0047] A vibration motor 4 is fixedly installed on the outer wall of the second storage box 3. When in use, starting the vibration motor 4 can cause the second storage box 3 to generate high-frequency micro-amplitude vibration, which effectively prevents the sponge blocks from bridging or sticking inside the second storage box 3 and ensures smooth material supply.

[0048] To enable the second tray 21 to flip and connect the two boxes 26, the two boxes 26 are pre-connected via a connecting strip 27. One of the boxes 26 has a connecting block 29 on its outer wall, and this connecting block 29 has mounting holes inside. Figure 10 As shown, the outer wall of the other box 26 is provided with a connecting end 28 corresponding to the position of the connecting block 29. The connecting end 28 is V-shaped or barbed. When the two boxes 26 are close to each other, the connecting end 28 can be inserted into the mounting hole of the connecting block 29. The elastic deformation of the V-shaped structure achieves locking and fastening, thus completing the stable connection of the two boxes 26.

[0049] like Figure 6As shown, a second mounting groove 24 is provided between the first mounting groove 18 and the second tray 21. The second mounting groove 24 is adapted to the width of the connecting strip 27 and is fixedly connected to the first tray 9. When the two boxes 26 are installed, the connecting strip 27 is located between the two second mounting grooves 24. The two second mounting grooves 24 further provide support and prevent the position of the two boxes 26 from shifting.

[0050] A control panel 32 is also embedded on the front side of the base 1 of this device. The control panel 32 integrates a microprocessor, memory and timing module, and the outer surface of the control panel 32 is provided with a display screen and operation buttons.

[0051] The memory is used to store preset process parameters and equipment operation data, including: the average weight of a single sponge, the number of sponges required to be filled into the box 26, the target total weight of the box 26, the cumulative number of finished products filled, the total running time of the equipment, and historical production efficiency data.

[0052] The input terminal of the control panel 32 is electrically connected to the weighing device 14 and the timing module. The output terminal of the control panel 32 is electrically connected to all the actuators, including the vibration motor 4, the stirrer 5, the drive motor of the roller 13, the first telescopic rod 11, the second telescopic rod 17, the third telescopic rod 30, the fourth telescopic rod 31, and the motor driving the movable arm 20, so as to realize centralized control and status monitoring of the fully automatic filling process.

[0053] In order to realize the statistics of filling quantity and efficiency calculation, the control panel 32 has a built-in counter. The counter is associated with the tilting action of the weighing device 14. Each time the sponge block is weighed and tilted, that is, the weighing device 14 rotates around the first connecting shaft 12 and resets once, it means that the sponge filling, splicing and unloading of a box 26 is completed, and the total count of the counter increases by 1.

[0054] The LCD screen of the control panel 32 can display the counter count in real time. At the same time, the timing module records the total running time of the equipment from startup to the current moment. The microprocessor of the control panel 32 calculates and displays the current production efficiency in real time based on the total number of finished products and the total running time. Operators can query the above statistical data through the control panel 32 at any time.

[0055] The above calculation process is to divide the total number of finished products by the total running time, where the total number of finished products is the number counted by the counter.

[0056] In the traditional manual operation mode, taking the filling of 8 sponge blocks as an example, the average time for manual operation is about 44 to 48 seconds per block, while the single cycle of this device takes about 11 to 13 seconds. After conversion, the filling efficiency of this device is about 3.5 to 4 times that of manual operation. The actual hourly output is about 75 to 85 blocks for manual operation and about 280 to 320 blocks for this device.

[0057] Working principle: The operator first inputs preset parameters through the control panel 32, including the average weight of a single sponge and the quantity filled at one time. The control panel 32 automatically calculates the target total weight and stores it in the memory. The operator first pours the sponge blocks to be filled into the second storage box 3 in batches, and inserts the first storage box 2 into the front end of the base 1. Then, the two boxes 26 pre-connected by the connecting strip 27 are placed separately. One box 26 is placed in the first mounting slot 18, and the other box 26 is placed on the second tray 21. After the device is started, the third telescopic rod 30 extends, pushing the insert 25 into the mesh outer wall of the box 26 in the first mounting slot 18, thus fixing the box 26. Vibration electric When machine 4 starts, the second storage box 3 vibrates. Simultaneously, the second telescopic rod 17 retracts, causing the clamping plate 16 to move to both sides, opening the lower outlet of the discharge pipe 15. Under gravity, the sponge block falls from the second storage box 3 into the discharge pipe 15 and slides down along the first transmission pipe 6. When the sponge block slides to the position of roller 13, the external motor drives roller 13 to rotate clockwise. The anti-slip structure on the outer wall of roller 13 drives the sponge block to pass through one by one, realizing single-block discharge. The sponge block falls onto the weighing device 14 through the second transmission pipe 7. The weighing device 14 detects the cumulative weight in real time. When the detected weight reaches the preset value, it sends a command to the external motor corresponding to roller 13 to stop the rotation of roller 13. 17. The extension pushes the clamping plate 16 to reset, clamping the sponge block at the lower end of the discharge pipe 15, pausing the feeding. The weighing device 14 rotates to reset. Subsequently, the weighing device 14 rotates and tilts around the first connecting shaft 12, causing the measured sponge block to fall into the box 26 in the first mounting groove 18. At this time, the counter built into the control panel 32 automatically increments by 1, and the cumulative completed quantity on the display screen is updated synchronously. The drive mechanism drives the movable arm 20 to move, causing the second tray 21 to rotate around the second connecting shaft 22 towards the first tray 9, driving the box 26 on the second tray 21 to move closer to the box 26 in the first mounting groove 18. When the two boxes 26 are completely in contact, the connecting end 28 is inserted into the mounting hole of the connecting block 29. After the splicing and locking are completed, the second tray 21 rotates in the opposite direction to reset, the third telescopic rod 30 retracts to make the insert 25 exit the mesh outer wall of the box 26, the fourth telescopic rod 31 extends to drive the second pusher 23 to move upward, and push the two spliced ​​boxes 26 upward. The first telescopic rod 11 extends to drive the first pusher 10 to move towards the first mounting groove 18, and push the assembly out of the first mounting groove 18 from the side, so that it falls into the first storage box 2. Finally, the fourth telescopic rod 31 and the first telescopic rod 11 retract, driving the second pusher 23 and the first pusher 10 to reset, completing one complete automatic filling cycle. Then, a new box 26 is placed again, and the above actions are repeated to achieve continuous production.
